The star sapphire has, since its discovery, been brandished as a strong, protective talisman, guiding travelers. Its central star caused inclusions is of great rarity, highly coveted.
Star sapphire is a corundum, a large family of stones including sapphires and rubies.
Sapphire comes from the Latin sapphirus, itself coming from the Greek σάπφειρος. Meaning simply precious stone.
Star sapphires, being simply sapphires with particular inclusions, are found in the same deposits as "classic" sapphires, mainly in Madagascar and Sri Lanka. It is however much rarer and more random to find them.
The majority of star sapphires are blue, but they can also be all the different colors of sapphire: pink, orange, green, yellow, lavender, gray, white and black. The most sought-after sapphires are a vivid, intense blue.
Star sapphire is, like all sapphires, composed of aluminum oxide crystals and colored by the presence of impurities such as iron, titanium or chromium. Star sapphire has the particularity of having inclusions of rutile needles, which are the origin of the central star of this stone.
Like all corundum, the strength of star sapphire is rated 9 out of 10 on the Mohs scale, making it one of the strongest stones.
